My Name is Fadi Abu Tahoun. I am from Jordan and currently live in Riyadh - Saudi Arabia. My thanks to Reef2Reef for featuring my tank as Reef of the Month spotlight. Keeping a reef here in this part of world is not an easy task. All of my equipment is bought and shipped from the USA to Saudi Arabia, and for live stock I have had to travel and drive more than a thousand miles to nearby countries like Bahrain and Dubai to get some coral frags and fish (until recently since I started helping a local fish store to order live stock from Indonesia and the Philippians so I can get my wish list).

I am in love in Acropora corals and Angelfish, and I always wanted to make a reef tank that has them all.

​

System Profile:

Display tank: 180 Gallons 72" X 24" X 24"

Glass or Acrylic: Tempered glass

Stand: Steel Stand

Sump: 40"L X 20"W X 18"H

Protein skimmer: Super Reef Octopus SRO 3000 In-Sump Protein Skimmer

Carbon/phosphate filtration: two TLF Phosban Reactor 150 (one for carbon, the other for GFO)

Return pump: Jebao DC - 12000 with manifold to feed media reactors

Water circulation: 2 Apex WAV

Lighting (display): 3 Radion XR30 Pro

Lighting (refugium): Kessil H380 Halo II LED Algae Grow Light

Calcium/alkalinity/magnesium dosing: Jebao Auto Dosing Pump DP-4

Auto top-off: Apex ATK

Heating/cooling: two ehim 300 heaters , and room AC

System control: Apex Classic Controller with WMX to control the radions, PMK for PAR monitoring , FMM for leak detection, and optical sensors

Other details: Dosing Acropower and Fauna Marin color elements.

​

Water Circulation and Flow Summary and Objectives:

I am trying to achieve the maximum flow from my WAV pumps with random flow profiles changing throughout the day, starting at 10% at early morning to 80-100% at regular hours.

​

Water Parameters:

Temp: 77 -78 f

pH: 8.1 - 8.3

Specific gravity: 1.026

NO3: 0.2 - 2.5

Ca: 420 - 460

Alk: 9.0 - 9.5

Mg: 1300 - 1350

PO4: 0 - 0.02

Ammonia and nitrites: 0

Lighting Summary and Objectives:

I have used the Apex PMK to measure tank par values at the start of the tank I am targeting values from 200 PAR at the bottom of the Tank to 450 PAR at the max tip of my corals. My program have 4 main color settings, sunrise , white light to boost growth, Ecotech Coral Lab AB+ at the main viewing time, then deep blue to give the colors an extra boost.

Photoperiod:

Display tank: 12 total hours, it starts with all blue sunrise for 1 hour, then 12K , 14K, followed by a mimic of Ecotech Coral Lab AB+ program, ended by few hours of sundown with deep blue only.

Refugium: On for 24 hours

​

Filtration and Water Quality Summary and Objectives:

I have a Heavy Bioload and feed my Angels a lot to keep them away from my corals. My main nutrition export method is via a relatively large refugium with the strong Kessil LED and a strong skimmer. Also I perform weekly 10% water change and small addition of Brightwell Microbacter7 and Fritz Monster 460.

​

Calcium/Alkalinity/Magnesium Summary and Objectives:

I dose Calcium and Alkalinity via an Auto doser. For Magnesium, I only test once a month and correct values accordingly. I use Bulk reef Supply Additives and baking Soda for Dosing.

Tank Inhabitants—Fish:

1. Emperor Angelfish(Pomacanthus imperator) From Juvenile To Young Adult

​

2. Coral Beauty Angelfish(Centropyge bispinosa) From The Philippines

​

3. Another Coral Beauty Angelfish(Centropyge bispinosa) From The Indonesia
